Precise geometric reconstruction is a valuable tool in the study of soft tissues biomechanics. Optical methods have been developed to determine the tissue cross section without mechanical contact with the specimen. An adaptation of the laser micrometer developed by Lee and Woo [ASME J. Biomech. Eng., 110 (2), pp. 110-114]. is proposed in which the laser-collimated beam rotates around and moves along a fixed specimen to reconstruct its cross sections and volume. Beam motion is computer controlled to accelerate data acquisition and improve beam positioning accuracy. It minimizes time-dependent shape modifications and increases global reconstruction precision. The technique is also competent for the measurement of immersed collagen matrices.

Aim: Minimally-invasive spinal surgery is increasingly being adopted worldwide. In this study, we evaluated the postoperative magnetic resonance imaging (MRI) findings and clinical outcomes of patients who underwent full endoscopic lumbar disk surgery.
Methods: Preoperative and postoperative 3rd and 6th month MRI features, visual analog scale (VAS) score, Oswestry Disability Index (ODI), and clinical features of patients who underwent percutaneous endoscopic lumbar discectomy between August 2009 and January 2012 were retrospectively analyzed.

Background: For restorative demands, increased vertical dimension of occlusion (VDO) is sometimes necessary, as facial changes can be perceptible.
Objectives: This study aimed to evaluate the perception of facial change due to increased VDO and associated soft tissue changes using 3D-scanned facial images.
Methods: Forty participants with healthy dentition and no loss of VDO were recruited.
Adult-Onset Pediatric-Type Follicular Lymphoma of the Parotid Gland.

Pediatric-type follicular lymphoma (PTFL) is an extremely rare B-cell lymphoma that primarily affects children and young adults, typically in individuals under 25 years old, with a median age of 15 years. Here, we report a rare case of PTFL in a 27-year-old adult male who presented with a slow-growing mass near his left ear. Initial CT scans of the neck revealed two oval-shaped, smooth, well-defined, homogeneously enhancing soft tissue density lesions in the superficial lobe of the left parotid gland.

The combination of hydrophilic arginine residues and hydrophobic tryptophan residues is considered to be the first choice for designing short-chain antimicrobial peptides (AMPs) due to their potent antibacterial activity. Based on this, we designed an arginine- and tryptophan-rich short peptide, VR-12. Peri-implantitis is a significant microbial inflammatory disorder characterized by the inflammation of the soft tissues surrounding an implant, which ultimately leads to the progressive resorption of the alveolar bone.
